      • DefaultCaseDiagramCanvas

        public DefaultCaseDiagramCanvas​(int width,
                                int height,
                                int minX,
                                int minY,
                                String imageType,
                                String activityFontName,
                                String labelFontName,
                                String annotationFontName,
                                ClassLoader customClassLoader)
        Creates an empty canvas with given width and height. Allows to specify minimal boundaries on the left and upper side of the canvas. This is useful for diagrams that have white space there. Everything beneath these minimum values will be cropped. It's also possible to pass a specific font name and a class loader for the icon images.

      • DefaultCaseDiagramCanvas

        public DefaultCaseDiagramCanvas​(int width,
                                int height,
                                int minX,

                                String imageType)
        Creates an empty canvas with given width and height. Allows to specify minimal boundaries on the left and upper side of the canvas. This is useful for diagrams that have white space there (eg Signavio). Everything beneath these minimum values will be cropped.
        Parameters:
        minX - Hint that will be used when generating the image. Parts that fall below minX on the horizontal scale will be cropped.
        minY - Hint that will be used when generating the image. Parts that fall below minX on the horizontal scale will be cropped.
